Degrees of Darkness

First published in 2017, now republished in 2021.

From the bestselling author of the addictive DI Bliss series and the compelling standalone novel, Fifteen Coffins, comes a dark, psychological journey into the nightmare world of a serial killer.

Nothing is ever entirely black or white.

Pre-teen girls are being abducted from their homes and their families murdered. When Frank Rogers, ex-DI with the Metropolitan Police, is told that his own daughter is missing, his son a victim, he sets aside his grief to help old colleagues investigate the case. 

Soon Frank’s face is all over the news. And in an unexpected turn of events, the killer contacts the police to say he is willing to talk. But only to Frank.

When the body of the first abducted girl is discovered, Frank realises the investigation has become a race against time to save his daughter’s life. 

In order to solve the case, Frank must work out how the killer is choosing his victims. To do that, he must first enter the killer’s mind. But is Frank able to drag himself into its darker reaches? And if so, will he be able to pull himself back?

“This is an awesome read that for me that put it on a scare factor alongside Stephen King and Thomas Harris.  The heart breaking opening will make most readers just stand back and take a breath. Frightening, terrifying and imprinted on your mind for every time you say goodnight to your children before you double-check and triple check your doors are locked and bolted again.”

"If I could have given this book more than five stars I certainly would. It is sensational and I think the best thriller I have ever read. I hope he writes some more. In my opinion it's not for the faint-hearted. Brilliant."

"Degrees of Darkness is an excellent read and it is one of my favourite books this year."

"It is brilliantly written, without excessive gore – a mark of a true craftsman. I absolutely loved it, and would HIGHLY recommend."

"A brilliant, hard to put down book that leaves you reeling, and thinking about it long after the final page. Excellent."

"If you read books of this genre then this is up there with the best."

“This book is simply brilliant from start to finish. I loved everything about it, from the memorable, unique and identifiable characters to the wonderfully deep, twisted and well thought-out plot.”

“What a fabulous story from the opening scene it just exploded into a world of pure crazy in the mind of one of the most damaged and twisted serial killers that I have read.”

“Tony has created a character who is evilness personified.”

"Gosh it's so eerie which makes you feel uncomfortable as the story gallops along at such a pace. At one point I had to put my Kindle down because I didn't want to finish the book.....It is that thought provoking and the evil characters are made to feel so real it scared the life out of me."

“Degrees of Darkness certainly took me on a journey to the dark-side and beyond! This is an intensely chilling book. The author suckered me in from the beginning and never really let go. My heart was in my mouth a lot of the time.”

“The characters are absolutely perfect. The author has built compassion and a dogged determination to survive into complex and realistic characters. He takes this realism to a whole new level as we learn how much a person can endure before there comes a breaking point and how that breaking point can cause a domino effect of actions that it is difficult to stop.”
